HEATING SYSTEM.

- T all whom it may concern:

Be it known that I, EDWARD DAVOCK, a citizen of the United States, residing at New York, in the county and State of New York, have invented certain new and useful I mprovements in Heating Systems, of which the following is a full, clear, and exact specification.

My invention relates to heating systems and especially to steam boilers.

The referred object, of the invention is to provlde an economical device for heating liquids, or vapors.

Another object of the invention is to provide, in connection with a steam boiler, means for heating water for domestic use, for room heating, or, for other purposes. It is the aimof the invention to utilize the waste heat in the combustion chamber of a boiler for heating water for use as feed water or for other uses, thus doingaway with the expense of installing and maintaining the separate heaters generally employed for these purposes.

The water heater is adapted to be installed in the combustion chamber of a steam boiler when the latter is built. or it may be placed in an old or already built combustion chamber at any time during repairs.

The invention will be first hereinafter described'in connection with the accompanying drawings, which constitute part of this specification, and-then more specifically defined in the claims at the scription.

In the accompanying drawings, where in similar reference characters are used to designate corresponding parts throughout the several views Figure 1 is a longitudinal vertical section through the setting of an ordinary form of steam boiler, showing a water heater mounted in the rear wall thereof and connected up with a domestic hot water tank,

of combustion from the fire box pass over the wall 5 into the combustion chamber, thence up along the back wall between it and the rear end of the boiler, thence below the back arch 100 and through the flues or tubes of the boiler, and finally up to and through the chimney 9. The water heater 14 is preferably placed 1n the rear wall'of the combustion chamber, and has a plurality of circulating pipes pro ecting therefrom, into the combustion chamber 4, be supplied to the heater 14 by a pipe 16 from any suitable source, and the hot water may be distributed through the. pipe 18. It will be understood that pipe 18 may be connected up with various heating appliances and the hot water *inay be conducted for use anywhere, and for. any desired purpose: The circulating pipes 15 add greatly to the heatlng surface of the heater 14, because of them being surrounded by the products of combustion whirling in the combustion chamber and, therefore, greatly add to the efiiciency of the heater, and when used as a feed water heater, will greatly increase the efiiciency of the boiler. By reason of the position of the water heater, none of the gases that flow direct from the fire box, through the fines to the stack and which are required to heat the water in the boiler, are used for heating said water heater, direct, but rather the slow moving whirling gases that follow the boiler setting and which also give up some of their heat to the brickwork, supply the necessary heating. These, and only these, are the heat units utilized in the present improvement and, consequently, little or no more fuel is required for the uses intended, when the hot Water heater is placed in the walls of a combustion chamber, than would have been required for operating the boiler without the hot water heater attached thereto. i

The hot water heater may be connected up with a domestic hot water tank 17, the water running from the tank to the heater through pipe 16, and from the heater to the tank through pipe 18. The heated water may be distributed via pipe 19 and used for domestic or other urposes.

It will be noted that in obtaining the benefits I obtain from my heater I do so without as shown at 15. Vater may i chambers hand that by placing my heater in the bacli wall of the combustion chamber,

I obtain the desired results. in this invention,*ll utilize or depend upon the whirling heat units, heretofore valueless and someelsewhere, for instance, in the fire wall or sides of a combustion chamber so that the whole interior of said chamber may be lined with them. H I I Having thus described my invention, what I claim as new and desire to secure by Letters Patent of the'United States is 1. The combination with a steam boiler and the setting for the combustionchamber thereof, of a water heater imbedded in the wall of the setting, a plurality of circul'at-r ing pipes projecting from-the water heater into, the combustion chamber, and means for circulating water*'through said heater, the

icirculatiori of the imbedded water heater being independent of the boiler-operation.

2; The combination with a steam boiler and the setting for the combustion chamber thereof, of a Water heater imbedded in the wall of the setting, a plurality of circulat.-' 1

1 ing pipes projecting from the watenheater into the combustion chamber, and means for circulating water throu b said heater, the circulation of the imbedded water heater be ing independent of, the boiler operation. I 3. The combination with a steam boiler and the setting tor the combustion chamber thereof, of a water heater imbedded in the rear wall of the setting below the back arch,

a plurality of circulating pipes projecting from the water heater into t e combustion chamber, and means for circulating water.

through said heater, the circulation of the pendent of the boiler operation.

Intestimony whereof I have signed my name to this specification.
